[yaml2obj] Fixing opening empty yaml files. Essentially echo "" | yaml2obj crashes. This patch attempts to trim whitespace and determine if the yaml string in the file is empty or not. If the input is empty then it will not properly print out an error message and return an error code. Differential Revision: https://reviews.llvm.org/D59964 A test/tools/yaml2obj/empty.yaml M tools/yaml2obj/yaml2obj.cpp llvm-svn: 357219

[yaml2obj/ObjectYAML] - Cleanup the error reporting API, add custom errors handlers. This is a continuation of the YAML library error reporting refactoring/improvement and the idea by itself was mentioned in the following thread: https://reviews.llvm.org/D67182?id=218714#inline-603404 This performs a cleanup of all object emitters in the library. It allows using the custom one provided by the caller. One of the nice things is that each tool can now print its tool name, e.g: "yaml2obj: error: <text>" Also, the code became a bit simpler.

[yaml2obj] - Don't crash on invalid inputs. yaml2obj might crash on invalid input when unable to parse the YAML. Recently a crash with a very similar nature was fixed for an empty files. This patch revisits the fix and does it in yaml::Input instead. It seems to be more correct way to handle such situation. With that crash for invalid inputs is also fixed now.
